Application filed February 14, 1910. Serial No. 543,843.

To all whom, it may concern:

Be it known that I, Trrorras C. Wswn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Iin rovements in Automatic Continuous Book-' rimming Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same.

This invention relates to a novel construction in a book trimming machine, the object being to provide a machine of this character which is simple in construction and operates with great rapidity and accuracy and consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings illustrating the invention: Figure 1- is a top plan view of a book trimming machine constructed in accordance with the invention. Fig. 2 is a sideelevntion of the same. Fig. 3-- is a front elevation o'f the same. Fig. -'l is a rear elevation of the same. Fig. -5- is a fragmentary detail transverse section on the line 55 of Fig. '7. Figs. and 7-- are vertical longitudinal sections on the lines 6-6 and 7-7 respectively of Fig. 1-. Fig. 8-'is a frog mcntnry vertical transverse section on the line 88 of Fig. 2. Fig. -9'- is a fragmentary detail section on the line 9-9 of Fig. -8. Fig. -10 is a detail vertical transverse section on the line 10-10 of Fig. Fig. 11-- is a fragmentary vertical transverse section on the line 11-11 of Fig. 1. Fig. 1-2 is a. fragmentary detail vertical transverse sectionon the line l9-12 of Fig. 2. Fig. 13 is a fragmentary detail vertical longitudinal section on the line 1313 of Fig. -1. Fig. -1-l is a detail bottom plan view of the guide shown at the lower end of Fig. 13-.

The present machine constitutes another embodiment of the broad conception of the invention forming the subject of Letters Patent .\'o. 1003679, granted to me Sept. I9. 1541, and the invention in the present machine resides in certain details of the cone-truetion as will be hereinafter-fully described and claimed. The machine illustrated and described in the aforesaid application is adapted more particnlarls to trim book pads of'somewhat limited thickness and upto a given minimum depth and length, its range of adjustment to handle book pads of varying dimensions being relat vely limited. This is, of course, an objection as it necessitates large establishments being equipped with machines of difierent sizes to handle book pads having a wide range of variation in dimensions.

The present invention has for object to provide means whereby book padsof widelydifferent dimensions may be handled in a single machine, the mode of operation and the advantages accruing therefrom being retamed. In other words the present invention relates solely to the embodiment in the machine of the aforesaid application of adj ustable book engaging and trimming means thus adapting the machine to handle the smallest as well as the largest size books (extraordinary extremes excepted) usually produced.

A primary object of the invention is to rovide means whereby the book pad may e engaged and firmly held ata point in very close proximity to the knife for trimming the front edge of the pad so that books having very short leaves (from back to free edge) may be trimmed in the machine, the diliiculty in the aforesaid machine having been that the points of engagement could not be brought sufficiently near the front trimming knife to handle books of small depth.

A second object of the invention is to provide means whereby book pads of greatly varying thickness may be trimmed without regard to length or depth thereof.

further object of the invention is to provide adjustable end trimming knives which may be moved toward or from each other and the interposed book carrying means to adapt them to trim books of greatly varying length, and to arrange the direction of travel of the knives from the back toward the front trimmed edges of the book pads so as to prevent tearing or burring the covers of the books.

The invention also has as further objects the provision of feeding devices for primarily positioning the book pads with relation to the front trimming knife; to provide means for readily and quickly elieeting adjustment of all lQt uisite parts to suit book pads of diti'erent sizes; to provide book demechanism comprises a trimming knife 1 so lar plane during the trimming operation.

livery mechanism and generally to provide simple and durable means for accomplishing all of the aforesaid objects.

The machine comprises a suitable frame in and upon which the operating mechanism is suitably supported. The said operating for trimming the front edge of a book or book pad, and two trimming knives 2 and 3 respectively, for trimming the ends of the book or book ,pad, the trimming planes of said knives 2 and 3 extending at right angles to the trimming plane of the knife 1. The cutting beds of said knives 1, 2 and 3 are rigid relatively thereto, but the frames 4 in which the knives 2 and 3 and their cutting beds 5 are carried are adjustable toward and from each other to vary the length of the books trimmed thereby. The said frames 4 are provided in their bases with grooves in which the keys 6 lying in grooves on the upper faces of the side pieces of the frame are received, the said frames and said side pieces being held against relative movement after effecting adjustment by means of bolts 7. The knife is mounted in the usual manner on the bar 9 and the latter is guided in the usual manner to move at an incline to its cutting bed, the said guiding means being partly disposed on the presser or clamping bar 10 which is vertically movable in the trimming frame.

Each of the bars 9 is movable between the vertical standards of the frame 4 and bars 11, the said bars 11 being secured at their upper ends to the frames -t and free at their lower ends. The knives in passing' downwardly to trim the book pads exert a pres sure against the said bars 11 by reason of the engagement of the beveled faces of said knives with the pad and to prevent said bars from yielding to such pressure, each of the same is provided at its free end with a bracket 12 provided with a longitudinal slot 13, the said brackets 12 of opposed bars overlapping each other and being secured against relative movement by means of the bolt 14 in an obvious manner. Each of the bars 9 is equipped at its ends with projections 15 each terminating in a substantially spherical end. This is connected by means of a pitman 16 with the crank of its operating wheel, said crank being similarly equipped with a spherical end thus forming universal joint connections between each pitman and the parts connected thereby which permits of adjustment of the frames and a movement of the pitman in an irregu- The front trimming knife 1 is rigid with the frame of the machine.

The said trimming frames 4 are disposed i upon either side of a table or supporting:

for the book pads moves. The said carrier consists of two belts 17 and 1S respectively, the belt 17 being trained over the driven pulley 19 and the idler 20 while the belt 18 is trained over a similar driven pulley 21 and two idlers 22 and 23 respectively, said idlers 20, 22 and 23 being disposed adjacent the front trimming knife 1. Said idler 23 is mounted on a shaft 24 journaled in free ends of arms 26 on a shaft which is journaled in t-hefree end of flanges 27 carried by the hearings in which said shaft 28 is journaled, the said bearings being vertically movable in the guides 29. Carried by similar diametricall opposite flanges 27 is a shaft- 30 connected by means of links 31 with one end of a depressing bar 32 adapted to bear upon the belt 18 to hold the latter firmly in its plane of travel while engaging the book pads. At its other end said bar 32 is vertically movable in suitable guides 33 and is held against upward more ment by means of set screws 34. The shaft 8 carrying the pulley 21 is journaled in bearings 35 which are vertically movable in guides 36. The vertical screw shafts 37 and 38 engage said bearings 35 and the bearings of the shaft 28 respectively, at one end and pass through suitable threaded projections of the frame at their other ends to etl'ect ver- 9 tical movement or adjustment of said bearings. Said screw shafts are turned by means of cranks 39 and 40 respectively, through the medium of the miter gears 41 in an obvious manner.

The crank 40 is mounted upon a shaft 42 which extends laterally across the machine and serves to simultaneously turn the said screw shafts 38 on opposite sides of the machine. The crank bt) is similarly mounted upon -a shaft 43 which passes through the hollow shaft 8 on which the said puliey 21 is mounted and at its other end carries the miter gear 41 which meshes with the similar gear carried by the screw shaft 37 on said side so that both said screw shafts 37 are actuated simultaneously to adjust the elevation of said pulley 21.

The said belt 18 carries cross plates it at intervals and in the projecting end portions of each of said plates lit reciprocating pluugers 5 are disposed, each pair of said plnngers 45 carrying a presser plate 46. as shown in detail in Fig. said presser plate being maintained normally at one limit of its movement by means of the compression springs 47. The said plungers and prcsser plates co-act with the belt- 17 and the table 16 and bar 232 to firmly clamp the hook pads between said belts 17 and 18.

The said idler 23 is raised and lowered at intervals between the insertion of book pads into the machine by means of the pitman H which is actuated by a cam as will be herebar over which one member 1' f th carrier 1 inaftcr described and with which the said shaft 30 is connected through the medium of a crank 48 thereon, the wrist pin of which is journaled in a. bearing,;i vertically movable in a guide 50 in? said pitman 47' and which is engaged by the crank-operated screw shaft 51 to adjust the position of said hearing -18) in said guide.

Movement is imparted simultaneously to both the said belts 17 and 18 by means of alever 5'2 (Fig. 2) pivotally secured at one end to the frame of the machine and which between its ends is provided with a longitudinal slot 53 in which a bearing 54 is slidable. In said bearing 54 is journaled the wrist pin 55 of a crank 56 rigidly mounted on a shaft 57 driven as hereinafter described and by means of which the said lever Zi'is rocked. Pivotally secured at one end to the free end of said lever 52 is a rack bar 58 which at its other end is reciprocally movable in the guide 59 disposed upon the free end of an arm 60 pivotally mounted upon the shaft 62 carrying the pulley 19 and which is capable of swinging on said pivotto accommodate itself to the varying position of said guide 59 due to the movements of said rack bar The latter meshes with a spur gear 61 loose on the shaft- 62 carrying said pulley 19. tigidly mounted on said shaft 69. adjacent said 5 )ur gear 61 is a ratchet wheel 63 having three teeth (in this instance) adapted to be engaged by the dog 64 pivotally mounted on said spur gear 61. Each movement of said rack bar 38 imparts movement in opposite directions to said spur gear 61. The movement o'f the latter in one direction is free and this movement is accomplished in a very much shorter time than the reverse movement owing to the fact that the crank en ages the lever TL? nearer the pivot thereof uring that pant of its revolution in which it throws the iever upwardly than upon effecting the reverse stuxke thereof durin which said dog 64 engages the ratchet wieel 63 and turns the shaft 62 through an arc of 120 degrees. T he movement of the said shaft 69- is imparted to the shaft 8 carrying the pulley 21 by means of a train of gearing eomprisingthc spur gear 65 on the shaft 69., the idle spur pini us 66 meshing with each other and one of which meshes with spur gear 65 and the other with a spur gear 67 rigid with the pulley 21. The said spur pinions 66 are revoluble in the free ends of the arms 68 and 61), one of which is pivotally mounted upon .each of said shafts 62 and 8 carrying said pulleys 19 and 21 respectively, and which at their free ends are pivotallv connected to-' gether by means of the linlvs 70. said pivotal connections being coincident with the axes of rotation of said idlers 36, the il'lllllllUiN of the latter constituting the pivotal connections between said arms and said links.

The relative dispositions of the spur gear 61, ratchet 63 and spur gear 65 on the shaft 62 and relatively to the frame of the machine is more; learly shown in Fig. 8 on an enlarged scale, as is also the hollow shaft 8 and the shaft 43 passing thercthrough to effect connection between the screw shafts 37 on opposite sides of the machine by means of which adjustment of the position of the pulley 21 is effected. vIt will be noted that vertical movement of the shaft' 8 does not affect the gearing between the same and the shaft 62.

The said belts 17 and 1S and pulleys 19 and 21 are equipped with coacting means for preventing thebelt from slipping thereon, this being obviously essential to maintain the clamping devices for the book pads in proper relative position to engage successive book pads inserted in the machine. Said means for preventin slippage comprise projections 72 on said: belts 17 and 18 which are adapted to enter recesses 73 in the faces of said pulleys. In order to permit the belts to be shifted on said pulleys to adjust the position of the clamps carried by the belt 18 so as to engage bool-z pads of varying depth, the faces of said pulleys 19 and '21 are provided with several sets of said recesses 73 spaced short distances apart so as to enable the projections 72 on said belts to be brought into engaging relation with either of said sets whereby said clam )5 are brought into engaging relation wit the book pad a greater or less distance from the trimming knife 1 as occasion may require.

-On either side of the plane of travel of the belt 17 and passing through the to plate of the frame of the machine, I provide what I will term disappearing stops 7% against; which the rear edge of the book pad bears when the latter is primarily inserted into trimming relation to the front trimming knife 1. Each of said stops it is adjustahly mounted on a horizontal bar 75 (Figs. 13 and i4) and is held against movement thereon by means of a set screw 76. The said bar 7 is disposed upon the free end of a projection 77 carried by a vertically reciprocating plunger 78 movable in the \ertical guide 79 secured to the lower face of the top plate of the frame. The said guide 79 is provided with a slot 80 through which the pin 81, on the plunger 78 projects, the said pin entering the longitudinal slot 82 in the free end of a rocking arm 83 mounted upon a shaft S4 (Figs. :2 and t3) journaled in l'iearings in the side plates of the frame. The said shaft St is rocked by meaus of the crank 85 carried therehyand pivotally connected with a pitman 86 which is actuated by a cam as will be hereinafter fully described.

The books may be fed into the machine by hand but it is preferred to effect such feed into trinnuing rtl ti n with th front trimming knife 1 by mechanical means so as to obviate the danger to the operator resulting from inserting the fingers into the trimming plane. To this end I provide a reciprocating plate 87 movable in guides 88 in the arms 89 of the side plates of the frame which said plate 87 carries an angle plate 90 slidable thereon. The said plate '90 carries a projection 91 which passes downwardly through a longitudinal slot 92 in said plate 87 and is connected by means of a link 93 with the free end of a lever 94 pivotally secured at its other end on a shaft 95 mounted at its ends in projections 96 of said side faces of the frame. Said shaft 95 is rocked by means of the crank 97 carried thereby, the wrist pin of which is connected by means of a link with the wrist pin of the crank on the wheel 98. The said plate 87 is reciprocated relatively to the arms 89 by means of the lever 99 pivotally mounted between its ends upon a projection 100 of one of the side plates of the machine and one end of which carries an anti-friction roller which is engaged in the cam groove 101 of the wheel 102, the other end of said lever being connected by means of a link 103 with a projection 104 on said plate 87. The said plate 87 is adapted to move rearwardly as the trimming knife 1 operates so as to leave an opening between the inner ends of said plate and the cutting bed of said knife through which the paper trimmed from the front edges of the books may drop, it being obviously essential to keep said feed table clear of the paper.

The machine is driven by means'of the drive shaft 105 carrying the pulley 106 and spur pinions 107. The latter mesh with the spur gears 108 at either side of the machine each of which carries a crank pin 109 connecting with the pitman 16' engaging one end of the knife bars of the side trimmers. The said spur gears 108 meshes with the idle spur gears 110 and the latterinjurn mesh with the spur gears 111 on the shaft 5? actuating the other pit-man 16 for operating the side trimming knives. The said spur gears 108 also mesh with spur gears 112. In the instance illustrated the latter are shownas being provided respectively with cam grooves 113 and 114. In the .cam groove 113 the anti-friction roller disposed upon the lower end of the pitman or 1ltlllger 47 is engaged, said plunger eing actuated thereby to raise and maintain the same raised during a given part of the revolutions of said wheel. .In the cam groove 114 the anti-friction wheel at the lower end of the plunger 86 is engaged. the same being raised and lowered at predetermined intervals thereby to actuate the tllfiill l kzlllllfl sto s 74. The said spur gears 112 mesh with the spur gears 11:) mounted on shafts actuating the front trimming knife 1. Said 1 intents and purp ses substantiall) Siluulluspur gears 115 mesh with spur gears 98 and 102- respcctively, the former of which is equipped in one face with the cam groove 101 actuating the lever 99 and the other of which is equipped with the crank pin 11G actuating the rock shaft 95 by means of which the plate 90 is reciprocated through the medium of the arm or lever 94. The cam grooves are shown as being formed directly in the several spur gears mentioned for purposes of convenience, it being understood. of course, that the separate cam wheels may be employed if desired.

The operation of the machine is as follows: At the time of insertion of the book pads, plate 90 and table 87 are disposed respectively, at the rearward limits of their movement. The book pad is inserted in front of the up-turned flange of the plate 90 and thereupon the latter together with the table 87 moves'forward, the said plate 90 traveling somewhat faster than said table. The table reaches the forward limit of its movement ahead of the plate 90 so as to close the opening in front of the cutting bed of the front trimming knife 1. At the same time that the book pad is moved forward the disappearing stops 74 are raised and the book pad pressed against the same by said plate 90. \Vhile the disappearing stops are rising and the book pads being fed forward, the pitman or lunger 47 is maintained at the upward limit of its movement thereby raising idler 23 and that part of the belt 18 lying between said idler '28 and the idler 22. As the book pad is brought into contact with said disappearing stops 74 the said pitman or plunger 47 drops thus lowering the idler 23 to the position shown in Fig. 7 and throwing the presser plate 46 into engagement with the top of the book pad thus compressing the latter between said plate and the belt 17. The plate 90 now recedes as does also the table 87 and the stops 74 drop out of the path of the book pad. The front trimming knife now moves downwardly and trims the front edge of the pad and upon completion of this movement, belts 17 and 18 are actuated to move the pad forward to the second position indicated in Figs. 2 and 7. Another pad is now inserted and the first namcd operation is repeated thereby advancing the first pad to the third position under the side trimming knives .2 and 3 where the ends of the pad are trimmed off. The said trunming knives 1, 2 and 3 are actuated at. slightly different intervals so that for example the front trimming knife hcgms its downward movement and this 15 followed successivclv at relatively very short, Hltt'P vals llV the knives l and so that (IH'lktlf said kiiivt-s finishes the trimming operation at a dill'crcnt time although to all. practical neously. The book pad now advances to the fourth position shown in Figs. 2 and 7 having been trimmed on its three edges and is now ready to be delivered from the machine. To effect delivi yfl provide a pair of bolts 117 trained over driven pulleys 118 (Fig. 8) disposed on either side of the pulle v 19 and mounted on shafts 119 journaled in hearings in hangers 120 and 121. On each of the shafts 119 is a spur pinion 122 which meshes with the idle spur pinion 123 and this in turn with the spur gear 121 on the shaft 62. The said belts 117 are trained at their other ends over idle pulleys 125 carrid by a shaft 126 jonrnaled in hearings in the free ends of arms 1'27 projecting from the side face of the frame of the machine.

It will be noted that the spur gear 12% is of greater diameter than the spur gear 122 so that said belts 117 are actuated'at intervals corresponding with the intervals of actuation of the belts 17 and 18 but at a. greater speed than the latter so that the pads after leaving the last osition shown in Figs. 2 and T are carried y the belts 17 and 18 upon said belts 117 and are immediately moved by the latter at greater speed in position to be removed by an operator standing at the delivery end of the machine.

By means of the bars 16 and 39. the bolts 17 and 18 are maintained positively in their respective planes of travel and the book pads thus firmly engaged between the same so as to prevent distortion of the same while passing through the machine. The upper face of the belt 17 passing from the idler 20 to the pulley 19 is disposed in a plane coincident with that of the cut-tin" beds of the knives 1, 2 and 3 so that book pads rest upon said cutting beds prior to their engagement by the presser bars of the trimming knives. This is a articularly requisite essential feature of t 1e machine as the trimming operation cannot be successfully performed without danger of distortion of the book pads unless the latter are caused to travel only in a given plane.

Any suitable means for maintaining belts 17 and 18 taut may be provided. In the instance illustrated I have shown set. screws 128 suitably disposed upon the frame of the machine and bearing against the standards in which the bearings 35 of the shaft 8 are mounted as an example of such helt tightening means.

The belts employed are preferably of steel although any other material suited to the purpose may obviously be employed without departing from the invention.
